Post by ChenCh »

After the UR10 robot in the model browser is imported into the scene, there are link and link1_visible under each joint. What is the difference between link and link1_visible?

"linkX_visible" objects are not dynamic and not respondable.
Those are used only for visual purposes.

"linkX" objects are dynamic and respondable, and their shape is typically an optimized and convex decomposed shape obtained from the original shape. This is done to help the dynamics engine perform faster and in a numerically stable manner.

Make sure to read manual page Designing dynamic simulations.
